Abstract (en)
A method of producing reduced metals is disclosed in which a mixture of a metal oxide and a reducing agent is heated by a burner such that the metal oxide is reduced to a reduced metal. Dry-distilled gas generated during carbonization of an organic matter-containing component is used as fuel for the burner. The sensible heat of exhaust gas evolved by the burner is utilized as heat for carbonizing the organic matter-containing component. Carbide derived by carbonizing the organic matter-containing component is used as the above reducing agent. This method yields excellent cost performance. An apparatus for reducing metal oxides is also disclosed.
